GlobalShortcut_win: fix XboxInput button mask in buttonName().

The controller ID is shifted 24 bits, so the correct mask is
0x00ffffff.

Also, 0x00ffffffff (40 bits) should have been a red flag, since
we're working with uint32_t types here.

This fixes button names for Xbox controllers that are at indexes > 0.
